2.3. ISOLATION

Converter   ADA-4040PC1   has   3-way   galvanic   isolation   on   the   levels   1kV=   or   3kV=,   depend   on   version   described   in   section

VERSIONS.

Fig 2. Isolation structure

3. INSTALLATION

This chapter will show how to use and connect ADA-4040PC1 to RS485, RS422 network and power supply.

In the purpose of minimization of disruptions from environment is being recommended to:

- apply multipair type shielded cables, which shield can be connected to the earthing on one end of the cable,

- arrange signal cables in the distance not shorter than 25 cm from powering cables.

- apply cable of adequate cross-section due to voltage drops for converter powering,

- use suppression filters for powering converters that are installed within a single object.

- not supply converter from power circuit device that generates large impulse interference such as transmitters, contactors.

3.1. ASSEMBLING

The cover of ADA-4040PC1 converter is adapted to assembly on TS-35 (DIN35) rail. To install the converter, should be mounted on

the rail upper part of the cover then press bottom part to hear characteristic „Click” sound.

3.2. COMPUTER CONNECTION

To connect ADA-4040PC1 to computer equipped with RS-232 or USB interface, is needed additional converter e.g. ADA-I1040 RS232

to RS485/RS422 converter or ADA-I9140 USB to RS485/RS422 converter; connected to ASCII port of ADA-4040PC1.

Typical connections of ADA- 4040PC1 to PC are shown bellow.
